CHAIN AND TRUCK GUIDE.

Application filed; April 9,

T 0 all ivhom it may concern:

Be it known that I, LEONARD E. Hmzs'r, a citizen of the United States.and residing at Detroit, in the county of \Vayne and State of hlic-higan, have invented new and Improved Chain and Truck Guides, ofwhich the following is a specification.

This invention relates to means for supporting conveyor chains forwheeled trucks and for guiding the trucks, and its particular object isto provide simple and effective means for supporting channel guides forconveyer chains and for supporting the guide bars for the trucks.

In many factories wheeled trucks are loa ded at different points andthen pushed into line to be slowly moved through enameling ovens or drykilns, or are moved along lines of workmen who carry out certain stepsin the assembling or finishing of the articles or machines on thetrucks, and it is often of advantage to have no tracks for such trucks,whi 11 makes means for guiding such. trucks through the ovens: or alongthe line of work men very desirable. The present simple combination,therefore, of a support and guide for the conveyer chain and of a guidefor the trucks has been found to be. of great advantage.

In the accompanying drawing, Fig. 1 is a side elevation of a truck and aguide therefor and for the conveyer chain. 2 is a transverse section ofthe guides and supports. Fig. 3 is a. section on the line 3-3 of Fig. 2.

Similar referen echaracters refer to like parts throughout the severalviews.

The truck 1 is shown conventionally to have wheels 2 and end bolsters 3provided with guide blocks 4. The conveyor chain is of well knownconstruction consisting of mid dle links 5 carrying fiat headed pins 6.and the side links 7 having slots 8 through which the heads of the pinsmay he slipped when the links 7 are at right angles to the middle links.At any desired intervals the middle links 9 are formed with. ears 10between which the dogs 12 are mounted on the pins 13. The tails 14 ofthese dogs are so heavy that the heads are held elevated so as to enga ethe bolsters 3 of the trucks.

These chains slide on channel bars 15 and 16. The return runs of thechains may be carried by the dogs 12 which slide on the web 17 of thelower channel 16 as shown in Fig. 3. The pedestals which form the 1924.Serial No. 705,352.

subject matter of the present invention each comprise a base 20 whichmay be attached to the floor by a bolt 21, two side members 22 and theweb 23 provided with the flanges or ribs 24, 25 and 26. The web also hasa perforated lug 27 to receive the bolt 28 and a flat face 29 to receivethe short angle iron bracket 30 having a horizontal leg 31.

The bolt 28, therefore, alone secures the pedestals to the channels andthe brackets 29 to the pedestals. The upper channel 15 is securely heldbetween the pedestals by the flanges or ribs 24: and 26. As thesepedestals are castings which require no machining, the chain guide canbe produced at minimum cost. The channels are rolled sufficientlyaccurate at the mills. An angle iron guide bar comprising a base flange33 and an upright web or leg 34 is secured to the brackets 30 by meansof bolts 35 and this flange 34: is of proper height to extend into theslots 36 of the guide blocks 4. The holes for these bolts are punched inthe base flange 33 and determine the posit-ions of the bolts 21.

The whole structure is very rigid. It can be quickly taken up and putdown in a new location when a move is found necessary, and the top edgeof the upright flange 34: is a. good guide for material trucks which areto be moved by this chain as above described.

I claim 1. In combination, two channel bars constituting guides andsupports for conveyer chains, pairs of pedestals supporting the bars,each consisting of a web having longitudinal flanges to position thebars, and a bolt extending between the pedestals of each pair to causethem to grip the channels.

2. In combination, two superimposed and spaced bars constituting guidesand supports for conveyer chains, pairs of pedestals supporting thebars, each consisting of a base and a web having longitudinal flanges toposition the bars, a bolt extending across between said bars from onepedestal to the other of each pair to cause them to grip the bars,brackets secured to the pedestals along one side of said guide barsforthe chains, and a third guide bar embodying a vertical web secured tosaid brackets.

3. In combination, two superimposed and spaced channel bars constitutingguides and supports for conveyer chains, pairs of pedestals supportingthe channel bars, each pedestal comprising a vertical web andlongitudinal flanges to position the channel bars, a bolt extendingacross between the channel bars and from one pedestal to the other ofeach pair to cause them to grip the bars, angle brackets secured by saidbolts to the pedestals along one side of said guide bars, and a thirdguide bar of angle iron secured .to said brackets with one flangeextending upwardly to serve as a guide for Wheeled vehicles.

4. In combination, two superimposed and spaced channel bars constitutingguides and supports for conveyer chains, pairs of pedestals supportingthe channel bars, each pedestal comprising a vertical web andlongitudinal flanges to position the channel bars, a bolt extendingacross between the channel bars and from one pedestal to the other ofeach pair to cause them to' grip the bars, angle brackets secured bysaid bolts to the pedestals along one side of said guide bars, a thirdguide bar of angle iron secured to said brackets with one flangeextending upwardly to serve as a guide for wheeled vehicles, and a chainslidable in said channel bars and embodying pivoted dogs adapted toengage and move the wheeled vehicles guided bv said angle bar.
